1) As yet, no, but there are more weapons coming in the Sommerlund rulebook. Range is kept pretty abstract in LWAG so if its a missile weapon, you can hit targets at Long or Far range.

2) Its entirely up to the Narrator but as written, weapons don't come with default qualities Some narrator's like to give default weapons qualities, while others treat them as upgrades for exceptional weapons. My personal take is to assume no defaults, and then experiment by giving npcs different weapons with qualities. So maybe one has a finely crafted sword (Balanced), or a brace of throwing daggers (Small, Throwing). Qualities add a certain crunch to combat so if you are happy with that, add as many qualities as you are comfortable with.
